Letters Patent No. 110,905, dated'January 10, 1871.

IMPROVEMNT IN VENTILATORS.

The Schedule referred to in these Letters Patent and making part of the same.

The nature of my invention consists in the einployment of an air-chamber; alsoa steam-vessel and a reservoir placed at the back or over the tiregrate of a room orhall, which, with appropriate tubing or pipes for supplying cold air from the outsideof the dwelling or from any part -o'f the room to the air-chamber, and for conducting the air heated in said chamber, and charged with moisture evaporated-from the reservoir in a pipe which encompasses a pipe charged with steam generated in the steam-vessel, and conveyed to any part of the room where the hot air is discharged, and the steam-pipe forming a coil for facilitating the discharge of the hot air from the circumscribing hotfair pipe isV returned to the condenser or reservoir, I am enabled to heat a room with fresh, warm air, charged with a healthful and agreeable proportion of moisture, the'heat utilized and evenly distributed,'while the room is well ventilated, and using only the' fire in the grate, stove, or furnace for such purpose, as IV will further explain by reference to the accompanyL ing drawing, of which- Figure l is a plan of part of a room or apartment provided with the apparatus;

Figure 2, a horizontal section 5 Figure 3, a transverse section, looking toward tiregrate and Figure 4, a longitudinal section of same.

vIn the said drawing- A indicates the floor,

B, the walls,

C, the chimney, and D, the fire-place of a hall or apartment of` a dwelling-house.

E is the air-chamber, placed in rear of the grate e.

F, the fresh-air pipe, which may lead from the outside of the dwelling or from' a distant part ofthe room into the ai'r-'c-hamberfl l G is the hot-air pipeT having its'inlet openingin the hot-air chamber-` It extends in a branch, H, upward'to a room'above,

cock, N, and an air or ballcoclr, O, iwithin the reservoir, for regulating the supply.

The water in this reservoir, on being heated, evaporates and mingles with the hot air in the chamber E, (the amount of evaporation being regulated by the sliding cover o from the outside ofthe air-chamher,) andis carried with the hot air throughthe pipe G and discharged into the `room at K, as warm, fresh air, chargedwith a healthful and agreeable proportion of moisture and la is a Adischarge-pipe, for surplus vapor and steam, into the chimney C.'

1, is the steam-vessel, placed in rear of the tiregrate'.v

This vessel has a supply-pipe, Q, 'and an air-cock, It, within the vessel, for regulating, the quantity ot' water required for steam; and saidvessel may also be supplied with water from the reservoir through'the pipe S- The steam generated in this vessel I' passes into the coil of pipe .'I, 4thence outside the air-chamber E, where it has a regulating and drain-cock, U 5 returns and passesintothe hot-air pipe G, where it has a branch, V, extending upward in'said hot-airpipc, and another branch, W, lpassing downward within said hot-air pipe, under the door, up in the opposite end of the room, through the bell-mouth K, where it forms a coil, X; returns, passes down under the floor, and up into the reservoir or condenser, where it discharges its exhaust-steam; vor may, if preferred, exhaust into the chimney O of the room through pipe ld.

The object of the steam-pipe within the hot-air pipe is to preserve the saine degree of heat in the air as it leaves the air-chamber until discharged into the room, and thereby cause a. current of air through the fresh-air pipe into the hot-air chamber, and thence through the not-air pipe into the room.

Z is a secondary cold air pipe', to take cold air from thesurface ot' theioor of the room through the register Z', and discharge into the. hot-air chainber.

b is, a register in 'the chimney C, for carrying off the lfoul air; and

e is the fire-grate, having at its back the steamvessel P, and provided with pivoted slats P P', when.

open for permitting the volatile products 0f combustion to escape into the chimney, or when partially closed retaining the greater portion of the heat in the fire-place for generating steam, and heating the cold air in the vairchamber, or radiating an increased quantity of heat into the room, as may be desired.

What I claim as new s-e -1. The steam-pipe T V W, and encompassing hotair pipe G H I, when used in combination with the the bell K of the hot-air pipe G HLfor the purposes hot-air ehamber E, steam-vessel P, and reservoir or substantially es setfforth anddescrihed. Condenser L, substantially as and for the purposes In testimony whereof I have hereunto set my sigdesoribed andv set forth. y nature this 21st dey of November, 1870.

2. The pivoted slats P P', &e., in combination with EDWARD MORTIMER DEEY. the hob-air chamber E, steam-pipel V W, and en compassing hot-air pipe G H I, substantially as and Witnesses for the purposes described and specified. ARTHUR NEILL,

3. The coiled steam-pipe or bulb k placed within EMILE MOLTZ.
